Just Python again!
Just Python!
This year has Visual Studio solution in the root, it includes projects for C++ and C#.
If you want to build C++ separately, something like g++ *.cpp -std=c++20 will do. Note that you will need C++20 support (tested on GCC 10.2 and VS 2019 16.8).
If you want to do the same with C#, just dotnet run should work (tested with .NET 5).
For Python, there is no "main" file, just run each day separately.
